Neo 875P and the AGP voltages?

Ok I have the settings as in my signature but i can run the card only at 4x, i dunno why but i suspect the voltages. The 8x should run at 0.8V but in Bios there's only 1.55V and Up does anybody has an idea what's wrong?

mathwizard
The voltage you refer to is Signal voltage
x4 1.5v
x8 0.8v
The connector voltage is the same for both specifications 1.5v
Suspect your problem is driver related

What would the agp voltage be???

the default voltage is 1.5
someone say change to 1.7 would be better , is that true????
my display card is nvidia geforce 4 ti with 8x .
does 8x need more power supply
if i change to 8x ,the temperature will be higher ??

The best voltage for any given AGP slot depends on a couple of things....The first and most important being how well(or close) the onboard voltage reporting winbond chip is.....The next thing is indeed the type of graphics card itself, and how much if any, do you have the Core and memory on the card Overclocked....But from everything that I have read about your G-F 4-Ti (and I also used to have one ), is that the AGP voltage for that Card should be Between 1.55 to 1.65 Volts....So I would start with 1.6 Volts and see how your games and benchmarks react ...If it does run stable at the "Default" AGP Voltage of 1.50, well thats fine too....But most cards will crash to desktop at a voltage of 1.50 while playing heavy graphics intensive games, so I find 1.60 to be the best........Sean REILLY875

Wats the AGP voltage on the MSI K7T266 Pro2?

i'm planning on upgrading the computer, but i need to know the voltage in order for it 2 work with the new, backwords compatible agp cards... is it the 1.5 volts agp, or is it the old 2x/1x standard?
Thanks,
-Luis

its an agpx 4 board so it can use 1.5v vga cards
any vga card basically evan agpx 8
as running them at agpx 4 looses little in performance

MSI 875P and the Ocz Gold VX PC4000

Hi,
I have try my new Ocz Gold VX PC4000 on my Msi 875p FISR. On bios in right that say 2.5v to 3.3v but I can't go over 3.0v. I have try it on another Msi 875p FISR but same thing.
Anyone have an idea?
Thank you.

My memory can handle without trouble and invalidating warranty 3.5v. I can't put my memory at 2-2-2-8 because need 3.3v. I have bought this motherboard because she is the only can support 3.3v without use OCZ DDR Memory booster.
You can watch memory spec at : http://www.ocztechnology.com/products/memory/ocz_el_ddr_pc_4000_gold_vx

AGP Voltage on an i875P NEO board & APG8X vid card???

I found this statement on intel's website:
"What add-in AGP cards can be used?
The D875PBZ AGP socket is keyed for Universal 0.8 AGP cards that comply with the AGP 3.0 specification or 1.5 V AGP cards that comply with the AGP 2.0 specification.
The AGP connector supports 8x, 4x AGP 3.0 add-in cards operating at 0.8V, or 4x,1x AGP 2.0 add-in cards operating at 1.5V.
Note: There is no support for AGP 2x operation or legacy 3.3V AGP cards."
Even though this statement is geared towards an intel motherboard, it looks like to me that if you have an AGP8X graphics card, then you better set the AGP voltage in the BIOS to 0.8V
By default, the NEO board is set to 1.5V
Any thoughts?

leave bios alone and it will sort it out

AGP Voltage @ 8x

Hi
I have query regarding the voltage that my GeForce FX5200 AGP card should be set to in the BIOS.
The 'spec' for the 875P AGP 3.0 slot states:
"AGP slot supports 8x/4x at 0.8v (AGP 3.0) or 4x at 1.5v (3.3v is not supported)"
Now according to CPU-Z, my FX5200 is running at 8x and my voltage setting is 1.65v, but shouldn't it be set to 0.8v for 8x?
(Come to think of it, I don't think the AGP voltage goes as low as 0.8v because I bleive the minimum voltage is 1.55)?
Maybe I'm not reading this correctly but I don't want to damage my board or AGP card, so I'd rather check it out with you guys.
Regards
Brave01Heart

No 1.55 is Fine ...As that is what MSI chose to use as the AGP Default......Some people run it at 1.6, But as most people don't realize that these newer generation Vid Cards get 90% of thier operating power from the +12V line (of the 4 pin Molex connector)....And even if you dont have a four pin molex, the only thing that you are doing is heating up your MCH (north bridge) with the the extra juice if you run it more then 1.5 Volts .....Sean REILLY875

9800 PRO 8x AGP Voltage?

I have an ATI-RADEON-9800-PRO-128Meg card.I run it at 8X AGP with fast writes enabled.I noticed that the voltage can not be adjusted below 1.55V in the BIOS.ATI states the the 9800-PRO 8x AGP should be 0.8V.AGP 8X (0.8v), 4X (1.5V).Core Center will not allow me to adjust it down below 1.50V.Am I going to ruin my card?It is all set on auto and not user.I just assumed that it was correct until I seen the specs on the card.If I use the SAMRTGART feature in the ATI control panel and change the AGP to 4x,the voltage stays the same at 1.55V.I do not have any problems with the way it is running now.But if it is going to cause damage to my card,should I remove the card until the BIOS is corrected?Now I will be worried about smoking the card.It is only a few months old.

Hi,
I'm a little bit confused now about these voltages. I understand that AGP 2x/4x/8x = 3.3V/1.5V/0.8V. I bought an RX9800PRO-TD128SP.
I have an ASUS A7N8X Deluxe motherboard with the following AGP specifications:
1 x AGP Pro/8X (1.5V only)
The VGA card replaced a Sapphire 9600PRO which only worked with 4x AGP and fast writes off (because in 8x AGP mode I've always encountered the same problem: the games quited to desktop or the monitor went in standby mode - in 3DMark03 it displayed a "monitor lost focus" message and went in standby mode).
So I installed the MSI product and I didn't have any problems with 3DMark03 anymore (I haven't tried playing yet). I have the latest ATI drivers and the AGP is set to 8x and Fast writes is on.
So we've arrived to the point where I'm confused: if my card runs on AGP 8x then the voltage must be 0.8 V. But how is this possible if the motherboard supports AGP 8x 1.5V only. Is this possible that the card can withstand an overvoltage or is this voltage just for signal purposes and all AGP 8x slots have 0.8 V (the ABIT motherboards - like NF7-S - support AGP 8x (0.8 V / 1.5 V). Or do I misinterpret something?
I wanted to find the answer in the knowledge base but I failed (page not found error):
Question:
How can I know what is my AGP card voltage?
Answer:
Most AGP4x & AGP 8x card are 1.5v

MSI FX5200-T128[8917]Has 5200Ultra Chip Will it need AGP Voltage rise

Hi,
Some where in this forum i saw that someone is talking about after removing the heatsink of 5200 and seeing it is 5200 Ultra ...It happened to me too...
My GPU is ought to be 5200 but under the heatsink it is 5200 Ultra
soo i need help about that how can i found vga bios for to turn its bios to 5200 Ultra's
My xp drivers saying it is 5200, after i updated bios will it be turn to 5200 Ultra...?? it must be but is there any compability issues known by anyone ??
And it is 5200 Ultra why it doesn't needs external power input[From PSU] like other Ultras have ?
If i rise the AGP voltage will it be helpful to use all power of 5200Ultra ?
thanx for your time ...
Sorry for my english

Since this issue is regarding a VGA card I'm moving your thread to the VGA Forum...

Agp voltage

hi,
i have a asus radeon 9800xt/tvd and every now and then i get weird thick dark bands running vertically at window xp pro desktop...also has narrower horizonntal banding as well. I reboot and it generally works after that properly. However, the other day it initialised the GART driver just before desktop loading and suddenly rebooted...then did it again. I went to bios and increased agp voltage from default 1.65v to 1.7v and it worked. Hssn't done anything wrong since. Was i right in assuming that was the problem and can i damage the card by doing so? Has this happened to anyone else? If so, how did you solve it and what was the cause?
Aspro
p.s. using latest catalyst drivers.
p.p.s. does anyone use the asus enhanced driver for their 9800xt/tvd instead of catalyst? if so why?

I have read about some people using 1.7v to solve certain problems although this was earlier 9600 cards I believe. I'm pretty sure you can't damge anything with that setting so if it works keep it. It is odd though that increasing voltage would solve this since the card gets most of its power from the extra cable you connected.

AGP voltage of gpu MS8808 ver:1A TNT2 Model64 32Mb??

I need to know the AGP voltage of gpu MS8808 ver:1A TNT2 Model64 32Mb
because I am getting a new Motherboard and it seems it just admit 1.5 volts AGP Voltage.
Thanks

juanpa74,
That is a 4x Vid Card. All 4x and 8x vid cards work with 8x mobos. All 4x and 8x mobos work with all 8X vid cards.
Here is an 8x Vid Card:
Take Care,
Richard
P.S. If the card does not fit the AGP Slot on the mobo, the voltage is wrong. (The only time this is not true is with some old Vodoo Cards that were put on the wrong PCBs.)

G4MX440 AGP voltage

Hi,
I have a G4MX440 AGP Video card and have brought a new motherboard and CPU combination. The motherboard (ASUS P4S800 / Intel P4 3.0G) warns that the AGP slot is 1.5 volts only.
Can anyone tell me the AGP voltage of the G4MX440 AGP Video card or where to find it. I still have the documentation for both the Video card and previous motherboard but neither mention this detail.
Thanks,
Regards,
Pauly.......

most AGP cards are 1.5V so you are ok

Neo 875P - Wheres me JUSB3 gone?:/

My query is pretty simple:) Where the hell is the JUSB3 socket? I have a JUSB2 socket and next to this is written JUSB3 but accompanying the writing is nothing but an empty space:/ Soooo whos stolen my extra usb port or am I just being stupid and its elsewhere on the board?

Hi
To: iyongski
Like WitchFinder, I also have the D-Bracket and two USB ports on the front of my case. I have a separate thick wire for each front USB port and each thick wire has four smaller wires with connectors marked:
USB Port 1: VCC1, Data -1, Data +1 and Gnd
USB Port 2: VCC2, Data -2, Data +2 and Gnd
If I use the D-Bracket and hook it up to the JUSB2 header, or I can connect my front ports up easily enough but that 8 wires and there is no wire for PIN 10 (USBOC). But if I connect my D-Bracket to JUSB2, I cannot also connect my two front USB connector wires to JUSB2.
To Assaf
I have the Neo 875P and it has 6 USB ports on the back panel, four under the mouse and keyboard ports and two right next to the LAN port. I.e. I have both LAN and USB ports together.

MSI 645 Ultra-C AGP voltage?

Would like to know what is the AGP voltage of the motherboard mentioned above, can't find it anywhere in the MSI site.
Asking because I'm using that mobo, and my newly bought ATI radeon 9600xt just won't work on it. When I say it won't work, I mean it crashes at any attempt to do 3d rendering(including direct3d test at dxdiag). My older card GF2MX worked pretty well.
Someone suggested that "cause new graphic cards are using 1.5V......... Old 4X AGP are only compatible with 3V graphic card. " How true is that? Could that be precisely just why my new graphic card won't work on my mobo? The board I mentioned above only support 4xagp true enough, but I'm not sure of the voltage. Does anyone know? The manual does not specify it.
Yeap, I installed and updated to the latest drivers.
Thank you!

My mobo can support 4x/8x AGP but I did use older AGP cards on it so no worries. I used to have an SIS 645D SA7 mobo from Abit that runs 2x/4x AGP Gart but also supports 4x/8x AGP cards as well as 1x/2x & 2x/4x AGP cards since 4x are found in all current AGP cards and on almost the new AGP cards, the RAMDACs are running on 1.5v(including the older GF4 series) so it's definately supported.
Just follow my suggestions on increasing your AGP Voltage for your ATI card in BIOS and use Omega drivers for ATI based AGP card. It won't harm your ATI card at all .
Lastly,I recommend that you do a clean un-installation of your old nVidia drivers or any older versions of AGP drivers before installing the new drivers. You may also be required to update your AGP Accelerator Gart driver for SIS based mobo, check the mobo's driver page for the latest version .

Setting up the correct voltages for PHC

Hi all!
I'm trying to use PHC to undervoltage my cpu, but I can't find how to set the correct voltages.
I installed phc-intel from AUR and /sys/devices/system/cpu/cpu0/cpufreq/phc_controls file contains the following line:
33:0 22:0 20:0 19:0 18:0 17:0 16:0 15:0 14:0 13:0 12:0 11:0 10:0 9:0 8:0
While in /etc/conf.d/phc-intel there's:
# voltage IDs to be set for all CPUs
VIDS=""
I read the wiki page about PHC, but I found only this:
[...]After the phc module is compiled and the lowest voltages are found[...]
and it's not really helpful...
Can anyone help me?
My CPU is an Intel i2720 processor.
Thanks a lot!

It seems that it's quite useless: it determines the lowest available voltage, but starting from 0 it sets 0 for each FID. The question is: how can the voltage be zero???
It isn't. I remember reading about this on the ubuntuforums thread about it a few years ago. Basically, if it let's you go to 0, it means that the hardware wont accept values below its actual minimum. So it's okay for you to set your FIDs to 0 because your hardware will just go to its minimum.

Is there anyway to read the unscaled voltage from a scaled virtual channel?

I am using DAQmx to read voltage from a SCXI chassis. Programmically in Labview I created a task with virtual channels and custom scales. Later in the program, I wish to view the scaled volatge and the raw voltage at the same time. Is there a property node which will allow me to do so?

Hi Fergusonhd -- yes, there is a way to do this --> Look in DAQmx-> DAQmxAdvanced-> Scale -> Scale Property node.
Drop it in and wire in your scale.(I did it by creating a constant for active_scale) Select the various attributes depending on the type of scale you created and manipulate your signals based on that information - For ex. if you created a linear scale, you could get information about the slope and intercept from this property node -- that being said, you can use this information and do the reverse logic:
[if original was Y=aX+b]
X = (Y-b)/a
where b is the Y intercept and a is the slope
Hope this helps
